Abstract

Systems, devices, and techniques are provided for operating a display and/or an illumination source based upon the direction of a user's gaze and/or a desired illumination level in a monitored area. One or more elements may be controlled with sensor input and application lighting preferences. For example, when a user receives a video call, light may be activated to illuminate their face. When the user is looking at the display, the display will be at the brightness necessary for the lighting conditions. When the user looks away from the screen, the screen may dim further and the lighting elements for the desk can brighten. Similarly, embodiments may adjust the lighting in a monitored location based upon lighting levels identified in other areas.

Claims3

Dependent claims

A system comprising:

a local illumination source;
a general room illumination source;
a light sensor configured to measure a level of illumination in a region;
and
a controller configured to receive a signal from the light sensor, and to control at least one of the local illumination source and the general room illumination source based upon the signal, to produce a selected illumination level in the region,
wherein the controller is configured to adjust the general room illumination source such that, when the local illumination source is on, the general illumination source is operated at a level that is not more than 50% of the illumination intensity at which the general illumination source is operated when the local illumination source is off and the energy consumption of the system is less than 50% of the energy consumption of the system compared to when the local illumination source is off.
